Study of pH in anthurium spathe provides clues to generating blues Flower color in plants is determined by pigments such as aurones, anthocyanins, and carotenoids. Research has found that the ultimate color displayed is dependent not only on the pigment present, but also on other factors, including cell shape, presence of metal ions, and pH, among others. Information about the role of pH in creating color has allowed plant geneticists to engineer new hues, adding to the beauty and diversity...

All animals face the challenge of deciding which chemicals in the environment are useful and which are harmful. A new study greatly improves our understanding of how animals sense an important class of potentially harmful chemicals: weak acids. The study appears online on May 16 in the Journal of General Physiology (www.jgp.org). Weak acids like acetic acid (vinegar) and propionic acid (present in fermented foods like Swiss cheese) are shunned by many animals, and with good reason. Many...

Researchers are developing a new type of biological and chemical sensor that has few moving parts, is low-cost and yet highly sensitive, sturdy and long-lasting. The "diffraction-based" sensors are made of thin stripes of a gelatinous material called a hydrogel, which expands and contracts depending on the acidity of its environment. Recent research findings have demonstrated that the sensor can be used to precisely determine pH - a measure of how acidic or basic a liquid is - revealing...

Color change confirms a new way to harvest energy from sunlight Professor Richard Watt and his chemistry students suspected that a common protein could potentially react with sunlight and harvest its energy "“ similar to what chlorophyll does during photosynthesis. The story of how they proved it sounds as colorful as the legend of the leprechaun who hid his pot of gold at the end of the rainbow. They started with citric acid from oranges and mixed it with the protein. Next they...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...

A pH meter, typically consisting of a special measuring probe connected to an electronic meter, is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid. The probe measures pH as the hydrogen ion activity that surrounds a thin-walled glass bulb at its tip. A small voltage is produce by the probe that measures and displays pH units by the meter. The meter circuit displays voltmeter in pH units instead of volts. The circuit of the pH meter consists of operational...
